HYDRocARBoN-BU RN ER FOR FURNAcEs.

SPECIFICATION forming part of Iletters Patent No. 412,481, dated October8, 1889.

Application filed August 9, 1888. Renewed August 15, 1889. Serial No.320,794. (No model.)

To all whom it may concern:

Be it known that I, JOHN B. DEEDS, a citizen of the United States,residing at Terre Haute, in the county of Vigo and State of Indiana,have invented certain new and useful Improvements in Hydrocarbon-Burnersfor Furnaces, duc.; andI do hereby declare the following to be a full,clear, and'exact description of the invention, such as will enableothers skilled inthe art to which it appertains to make and use thesame.

This invention relates to certain improvements in hydrocarbon-burners;and it has for I its objects to provide for effectively and thoroughlyburning liquid fuel in various furnaces, as will be more fullyhereinafter set' forth in this specification andpartiularly pointed outin the claims.

The objects of 4my present invention I accomplish by the meansillustrated in theaccompanying drawings, in which- Figure 1 represents asectional View of my improved burner; Fig. 2,' a sectional view ofamodification of the burner; Fig. 3, a sectional view of a portion of afurnace, showing my invention applied thereto.

Referring to the drawings, the letter A indicates a retort or chamberconstructed of metal or other suitable material, which is ex-V tendedupwardly at one side, as indicated in y top b, extending upwardly at oneside toward the upwardly-extended side, an opening or slot beingleft-between the extended side and the top for the escape of the vaporsor gases to be burned. At the side opposite the said extended side theretort or chamber is provided with perforations or a slot K' for theadmission of air, and through said side extends a pipe B, connected witha suitable liq# uid-fuel supply and a cock or valve, by means of whichliquid fuel in regulated quantities may be delivered to said retort. y

The letter C indicates an injector connected with a steam-generator orair-supplying device, located above the top of the retort in suchposition that a jet or series of jets of steam or air may be injectedagainst the ycurved portion of the top, inimmediate proximity to theopening through which the gas or vapor escapes, so as to meet the flameat such pointto insure a proper draft and effect perfect combustion ofthe fuel.

In the modification shown in Fig. 2, the injector enters the retortbelow the top, so that the current of steam or air may be injecteddirectly into the said retort, where it commingles with the gases orvapors generated therein, and insures perfect combustion at the point ofescape.

As shown in Fig. 3 of the drawings, the construction of the burner ismodified, the top in this case being raised at the center, a slot orperforations being formed at the apex of the raisedportion for theescape of the vapors or gases generated in the retort, the combustion ofsuch gases or vapors being. eifected at the point ofescape.

In this instance two injectors are employed, one 4at each side of theraised portion of the top, and so located as to inject the steam or airfrom each side upon the burning fuel at the point of combustion.

The burner is designed to set inthe lower part of the fire-box of afurnace, and the oil or other liquid fuel is fed into it in properquantities by means of the oil-feed pipe. The fuel, being ignited, soonheats the retort to a sufficient temperature to vaporize the fuel orconvert it into gas, which, escaping at the exits provided therefor,burnsv in the combustion-chamber of the furnace, the thorough combustionbeing insured bythe blast of steam or air injected. y

In order to regulate the quantity of steam or air supplied, the injectoris provided with a controlling valve or` cock at any suitable point.

It will be perceived that the burner as thus constructed not only servesas a gas or vapor generator, but by taking in the airl at one sideproduces a vaporous or gaseous mixture of such nature as to burn with anintense heat, which is further intensified by the current of steam orair injected, rendering the combustion of the fuel complete, so as toavoid the production of smoke or of tarry or solid deposits, which wouldclog the dues of the furnace and interfere with its operation.

I-Iaving thus fully described my invention,

l'what I claim, and desire to secure by Letters Patent,is-

1. A hydrocarbon-burner consisting of a IOO suitable retort or panhaving a curved top, and a portion thereof elevated and provided with anescapeopening for the generated gases, and also having air-inlet K andliquidfuel-supply pipe, in combination with asteam or air injector,whereby a current of steam or air may be injected into the ignited gasesto increase the draft and insure perfect combustion, substantially asspecified.

2. The combination, with a furnace, of a hydrocarbon-burner having acurved top and a portion thereof elevated and provided with an openingat the apex of the elevated portion, and the same also having inlet K, asuitable liquid-fuel-supply pipe, and an injector, whereby air or steammay be injected into the said furnace into the ignited gas or vapor,substantially as specified.

In testimony whereof Iafx my signature in presence of two witnesses.
